<body>
Provides support for describing and applying textual document editions.
<p>
A complex textual edition can be described by a tree of <tt>TextEdit</tt>s. An edit
can be applied to an <tt>IDocument</tt> by calling <tt>TextEdit.apply</tt> or by 
using a <tt>TextEditProcessor</tt>. Applying a text edit can record a reverse edit
description that can be used to undo the edition.
</p>
Use the standard edit kinds to describe the basic document editing operations:
<ul>
  <li><em>replace</em> a document range: <tt>ReplaceEdit</tt></li>
  <li><em>delete</em> a document range: <tt>DeleteEdit</tt></li>
  <li><em>insert</em> text: <tt>InsertEdit</tt></li>
  <li><em>track</em> a range while the document is being modified: <tt>RangeMarker</tt></li>
</ul>
<p>
Other subclasses of <tt>TextEdit</tt> exist for specialized tasks. Use <tt>MultiTextEdit</tt> to
compose a complex edit tree, or subclass it to provide a custom edit.
